Your broker will confirm your identity through your passport, license, or national ID. A copy of a utility bill or bank statement will also assist with verifying your address. The broker requests the financial and tax information to comply with U.S. government laws and Commodity Futures Trading Commission (CFTC) rules.
Once your account and margin agreements have been approved, you need to fund the account to start trading. It should be noted, however, that some of the leading online forex companies do not offer accounts to U.S. customers.
